I'm looking for the title of a series of novels I read as a teenager. I only have vague recollections but this is what I remember:
Written in the 70's or 80's.
An ex United Nations soldier commands a team that prepare potential colony worlds for habitation, eliminating any potential threats, constructing basic hab-units.
They use exoskeletal suits similar to the Powerloaders in Aliens.
I think the team were recruited from prisons and are offered pardons if they join. Each member is recruited due to their special abilities (skills not powers).
They become a troubleshooting team and each novel is about them overcoming the obstacles to colonising a specific planet.
I have a definite recollection that the United Nations was somehow involved.
Does anybody recognise this series?
